Application filedS'eftember 7, 1885. Serial No. 176.384.. (No model.)

To all whom it may concern:

Be it known that I, EDsoN L. BRYANT, of Ansonia, in the county of New Haven and State of Connecticut,have invented anew Improvement in Lamps; and I do hereby declare the following, when takenin connection with accompanying` drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specilication, and represent, in

Figure l, a side view in half-section; Fig. 2, a horizontal section cutting through the opening F in the ring E, showing the openings as offset when closed; Fig. 3, the same, showing the ring turned to bring its opening to register with that in the fount.

This invention relates to an improvement in that class of lamps in which a tubular wick is employed,with an air-space within it, through which air is supplied to support combustion, commonly called Argand burners, and particularly to that class in which the fount is made from metal, and such as commonly used in standard lamps, in which the standard is made from pottery, of' a cylindrical standard shape, with a cavity in the top, into which the fount may be placed, and so that the standard forms an ornament surrounding and hiding the fount, but applicable to other classes of founts. In this class of lamp a filling-opening is usually made in the top of the fount itself, closed by a screw-plug. Such a filling device not only detracts from the finished appearance of the fount, but it is difficult to determine the depth of oil in the fount, so that in filling it frequently overflows.

The object of1 my invention is to adapt a concentric ring to the fount with afilling-hole through the fount, and a corresponding hole through the ring, so that the ring being turned to bring the holes to register the lamp may be filled, or the ring may be turned to cover the opening; and the invention consists in the construction hereinafter described, and particularly recited in the claim, and whereby the ring is readily applied and securely held to the fount. l

A is the fount, which may be of any of the usual constructions. As here represented, it

is such as employed in standard lamps, and

adapted to be set into a receiver, the fount being constructed with an 'annular rib, a, to rest upon the top of the support. The upper part, B, of the fount is extended upward in any convenient or ornamental shape, but circular in horizontal section, and so as to form an outwardly-projecting annular rib, b, below the top of the portion B of the fount. The part B extends up, and is soldered at its upper edge to a short tube, C, within which the wickholding tube D is arranged in the usual manner.

Around the upper part of the fount, and above the rib b, a ring, E, is applied, in shape corresponding to that portion of the fount. The upper edge of this ring stands beneath an annular rib, d, on the tube C. The ring E is first applied to the fount, then the tube C introduced, the lower edge of the ring restlng upon Vthe rib a, andthe rib d forming a support for the upper edge of the ring E, and so as to prevent vertical movement of the ring E, yet leave it free for rotation.

Through the ring E is an opening, F, and through the corresponding portion B of the fount is a like opening, G. (See Fig. 2.) When the ring is turned, as seen in Fig. 2, the opening through the ring is brought onto the solid portion of the fount and away from the opening G; but when the two openings are brought to register, as seen in Fig. 3, then there is a clear opening into the fount,through which the oil maybe poured, and the opening is so large that the rising oil is readily seen, and overflow is easily avoided. The opening in the ring F appears as apanel in the fount, and is more ornamental than otherwise. A stud, e, projects from the fount through a corresponding slot, f, in the ring, and so that the rotary movement of the ring is limited, and so that the proper registration ofthe two openings will be indicated by the stud.

From the wick holding, or adjusting tube a ring, H, projects, ,by which the tube may be rotated in the usual manner for adjusting the wick-a device too well known to require illustration or description in this specification, as such adjustment constitutes no part of this invention.

Above the adjusting-ring H, an d over the wick-tube D, the chimney-holder is set. The

IOC)

base I of the chimney-holder curves outward and upward to the chimney-rest J. The base is perforated for the admission of air. At the lower edge the base is constructed with an upwardly-projecting flange, h, to embrace the tube, and so as to be thereby supported, resting on the ring II. The chimney-rest J is con centric with the tube D.

From the chimney-rest there is a cylindrical upward extension, K, to substantially the base of the flame. This extension forms a wall around the tube D, but so as to leave a considerable annular space, L, between the two,

into which openings through the base admit air. The wall K is of less diameter than 4the chimney M, so that there is also a space between the chimney and the said wall K.

Through the lower part of the wall K, and within the chimney, openings i are made for the passage of air from the space L into the space between the wall K and the chimney.

Near the upper edge of the wall K an annular series of springtongues, Zare arranged. These are best formed as apart of a ring, m, the ring constructed to embrace the upper end of the wall K, the tongues turned outward,so as to incline downward and project radially from the wall K, the length of the tongues Z being such that they impiuge upon the inside of the chimney M, as shown, and so that as the chimney is set upon thc burner and passes down to its rest it compresses the springs to some ex` tent, and so that the chimney, when on its rest, will be concentrically supported. The springs adapt themselves to slight variations in the internal diameter of the chimney. The inclination of the springs is such that while they hold the chimney for all practical pur-v poses it maybe readily removed when required.

I am aware that a series of radial spring- 4o tongues to support a chimney has long been well known, and therefore do not claim,broad ly, such chimney-holder. l

I do not wish to be understood as claiming, broadly, an annular ring having an opening 45 through it, and arranged so that by turning the ring al corresponding opening into the lamp will register with the said opening in the ring, the said ring being adapted to open or close the said opening into the fount for the 5o purpose of filling, as such I am aware is not new. Neither do I wish to be understood as claiming, broadly, radially-projecting springs to impinge upon the inside of the chimney as a support therefor, as such I am aware are 55 not new; but

A lamp fount constructed with the upward extension B, of circular shape -in horizontal section, the said extension constructed 6o with an opening, G, into the fount, the said extension provided with the annular rib d around its upper edge, combined with the ring E, surrounding that portion of the fount in which is the opening G, the upper edge of 65 said ring resting beneath said rib d, and the said ring constructed with an opening, F, corresponding to the opening G- in the fount, substantially as described, and `so that said ring may be rotated around the part B of the fount 7o to bring the openings F G inthe two to register or to close the same.
